X clients

An X client is an application that requires the service of an X server for it to be displayed. All the GUI applications that you use on a Linux system are examples of X clients (xterm, mozilla, xcalc etc).

1. Make sure you are still logged in at the 1st virtual console as the super user.

2. Also make sure that you still have X server running in the background on tty 7. Type:



You should get an output similar to the one above.

4. Now switch to the 7th virtual console to view the output of the above command. Type:



5. Use the mouse to click anywhere in the xterm window you launched above. Launch the xclock

7. To close the browser, click on mozilla’s file menu and select the “Quit” button.

8. Now kill all the X clients you have running and also kill the Xserver hosting them. Type:
